If you press the function button whilst powering on The Oasys,it prints out a discount Voucher which you can redeem against a future Purchase of a Korg Kronic.


I've never opened the Oasys up to look at the switches/Board etc to that degree......but can anyone confirm if Korg actually fitted one of those push switches on the PCB under the Function Button.

Each time you press the function botton I think it puts a red face of a korg representative.

That should be its function now.

Please try to stay on topic to avoid wasting time. This should be an important topic in the near future. Thanks.
The FUNCTION button is explained here:

The "function" comment was supposed to be a joke - a bit like the "function" button itself

My experience with the Korg service is mixed.
This summer, during our bhajans, suddenly some sparkles came out of the electric circuit and there was no light or current anymore in the house. The transformer had burned down and that was the end for now.
I phoned to the music-store next day and they phoned to Holland, where the main representative of Korg for Benelux is residing. As they didn't want to send the Oasys (88) the Belgium representative would come to Luxembourg and take it in his car to Holland. As the screws on my touch panel were broken since 2 years, I thought this was a good occasion the repair them also. I never wanted to ship the Oasys to Holland only for that. So I found a way to put some plastic behind the panel, so it stayed half up at least. I had also safe copies of all my programs on an external HD so that was also no problem if maybe the HD was also dead or some other circuits.
In the mean time I was leaving 5 weeks for India, so I was not in a hurry. In India I got the news that my Oasys had arrived in Holland for repair.
When I was back in September, there were still no news from Holland. The music-shop phoned there and they said they had to wait for the transformer who had to be send to them ( by Korg USA?) and that they will let us know when it is ready. After 2 more weeks the music-shop told me that the Oasys was ready and OK, but that they could not fix the defective Touch panel. That would take again some more weeks. I could decide if I wanted it directly or go on waiting. So I decided to have the keyboard back and go on with my plastic "ersatz".
A week later I got the Oasys back and it works as good as before. It was only the transformer who was damaged.
Because of the long waiting time and probably the guilt, because they could'nt fix the panel problem, I was not charged for the whole operation. This was also a good point.
So to conclude, you see why my experience is mixed. The service was partially first class, as the Oasys was brought specially in a car to Holland, that is was repaired for good in regard to the electrical shortcut, but that it
takes so much time ( 3 months) and the impossibility to repair the 2 screws in the back of the touch panel are really not professional. Its up to everybody to judge my experience.
And I'm glad that not more has happened, because I don't know if it would still be OK.
But now Korg gave us this Kronos"ersatz" if serious things happen, which makes me frustrated and secure at the same time!

Two points:

1. What other keyboards use the same keybed as the OASYS 88? Can some cheap Fatar MIDI keyboard be purchased over eBay to raid for its keybed for the OASYS 88?


2. Here's a pointer to an old thread with some useful pointers to OASYS spares:

Kevin.

Thank you, Kevin, for that good link.

If anybody has current info about where to buy spare parts these days (motherboard etc.) please, post it here for all of us. Thank you.

Regarding battery replacement I wrote this in another thread:

"It's easy, please read the short explanation how to do it on Parameter Guide p. 1093-1094. You have to switch the power OFF before you start. DON'T open and manipulate inside the OASYS while it's powered on - especially if you are not a professional technician - because you may damage it or you can get an electric shock.
Martin Hines took interior shots - see this post. Picture 4 shows the coverplate to be removed. Picture 5 shows the battery itself."

Has anyone posted a link to, or offered the Oasys Service manual on this forum yet ? Would Korg ( or anyone ) get the shits with us doing that, or now that it's officially an old discontinued model is it no longer an issue ?

I am sure that more than one of us has a soft copy of the manual, and it might be a good time to offer/share it with other users. It contains circuit diagrams of most boards which may not much use to anyone, but it does have assembly drawings and system schematics which may help with removing/replacing/repairing some parts for anyone with an electronics interest. It's certainly helpful for identifying part numbers if you need to order spares.

I doubt that there is an Oasys that still has a valid warranty, and I am sure the service agents around the world will lose interest in repairing these when the new models start rolling into their workshops.

My website is currently down but I shared an old post about replacing the bad tactile switches in OASYS. It's a PDF with high-res photos (24 MB). Downloadable here.

I'd strongly advise trying to clean the switches first, before replacing them.

Thank you. From what kind of dirt (dust, rust) and what is the proper way to do the cleaning? With compressed air or some "contact enhancement fluid"?

I always used my OASYS in clean and dry environment - in my home studio or few times on stage - and took care of it. Dust cover, flight case, washing hands... .

Dan, please, what is the proper way of cleaning you advised?

Dan writes manuals and albeit great ones, I'm unsure if he even knows how to do a correct cement mixture, needlework, or even anything more than use a wall-plug to plug in instruments(?)

Akos, you have to first disassemble the circuit board from the holder on the top plate (the one you lift up to get underneath the hood)

From there, you have a better "chance" of getting into the sliders.
But these sliders are constructed in a way, that replacement is almost the 'necessary' step to take.

This is because they are not 'open' but rather 'closed', capped in a housing.

Always, as with all other things too, use the lesser drastic method first.

1-compressed air - make sure to get some dust out, and not just spray so it moves around inside the slider.

2-electronic cleaning solvent/contact spray

3-replacement

I would always choose option 3, as the others above will most likely fail at some time later down the road.

"Prevention is better than cure" is a good expression that could apply here, hence always use a dust cover

If you don't have a dust cover, then use your wife's old wedding dress

Hi Hedegaard, you obviously haven't read my story about replacing the switches.

My question still stands: Dan advised something and I would like to know the details from him.

@ Hedegaard

Akos has done a great photo essay on replacing the O switches - an article which proves that it is not easy but is doable! Beyond me I'm afraid.

So anything that Dan can prescribe will be useful as my value increment switch is inop and I don't really want to take my O down three floors of my house, pack it up (in a box that is not original) and send it to Korg UK - and be without it for a couple of weeks!
